Animal Farm is Established

"Major's speech had given to the more intelligent animals on the farm a completely new outlook on life. They did not know when the Rebellion predicted by Major would take place,
they had no reason for thinking that it would be
within their own lifetime, but they saw clearly
that it was their duty to prepare for it. "
-narrator, chapter 2
This perfect logic led the animals to taking over the farm soon after and their freedom.
